A novel elliptically polarizing plate is disclosed. The elliptically polarizing plate comprises a polarizing film, two protective films respectively disposed on a surface of the polarizing film, and a retardation film disposed adjacent to at least one of the protective films, wherein an absorption axis of the polarizing film and a slow axis of the retardation film are perpendicular or parallel to each other; the retardation film has an Nz value, as defined according to (Nz=Rth/Re+0.5) by using an in-plane retardation Re and a retardation Rth in the thickness direction, of from 0.3 to 0.7 and an in-plane retardation Re of from 150 to 400 nm; and the protective film adjacent to the retardation film comprises a cellulose acylate and has a retardation Rth in the thickness direction of from −30 nm to 30 nm. |
